CFD framework for compressible flow solvers using compact finite differences and Runge-Kutta timestepping methods. Parallelized using MPI and 2-D pencil domain decomposition that uses a C++ translation of the 2Decomp library.
Current default (and only up to date) solver is the CurvilinearCSolver, solves compressible Navier-Stokes equations on a single, generalized curvlinear block using the formulation of Visbal & Gaitonde (2002, JCP). There's also a uniform grid, compressible solver with fully-expanded viscous terms that needs to be brought up to speed in DepreciatedSolvers.
libpng - required for generating flow-field images
boost/program_options - required for parsing flow solver options inputs
whatever mpi you'd like - if you like running things in parallel
*FDTYPES = CD2, PADE6, PENTA10
CD2 - Second-order Central Difference Scheme
PADE6 - Sixth-order Tridiagonal Compact Pade Scheme (Lele, 1992)
PENTA10 - Tenth-order Pentadiagonal Compact Scheme (Lele, 1992)
RKTYPE = TVDRK3, RK4, KENRK4, LSLDDRK4
TVDRK3 - Total-Variation Diminishing RK3 scheme (Shu & Osher, 1988)
RK4 - Classic Fourth-order RK method
KENRK4 - Five-stage Fourth-order Lowish-Dispersion RK4 (Kennedy et al, 1999)
LSLDDRK4 - Two Stage, Eleven Step Low-Storage, Low-Dispersion-Dissipation, RK4 (Stanescu & Habashi, 1998)
FILTERTYPE = COMPACT8, COMPACT10
COMPACT8 - Eigth-order compact filter (Giatonde & Visbal, 2000)
COMPACT10 - Tenth-order compact filter (Giatonde & Visbal, 2000)
LESMODEL = NONE, VREMAN, DSM
NONE = The special DNS LES model
VREMAN = Standard Vreman SGS (Vreman, 2004)
DSM = Compressible Dynamic Smagorinsky (Flavor thats in Nagarajan et al., 2003 with some differences from Martin et al., 1999)
LESAVERAGING = NONE, XI1_AVG, XI2_AVG, XI3_AVG, LOCAL
XI1_AVG, XI2_AVG, XI3_AVG - Averaging along cartesian (pre-transformed) directions
LOCAL - Using a filter function to do a local filtering/averaging of quantities
DSMTESTFILTER = Options for test filter for dynamic procedure
1 = Explicit Commutative Test Filter (Vasilyev, 1999) (Five Vanishing Moments, Case 10, Table I)
2 = Pade-Type Commutative Test Filter (Vasilyev, 1999) (Five Vanishing Moments, Case 2, Table III - Much Sharper Filter)
DSMUSETAUKK = Whether or not to use the model for sgs energy, usually small for low turb Mach and gets added to pressure
DSMCOEFFRANGE = Whether or not to dump the range of the Smag. constant, CI, and turbulent Prandtl number to output
